After collaborating on some development programs over their 18-year alliance, it looks like Renault and Nissan are ready for the most important collaboration yet: a common electric vehicle platform for the next generation Renault ZOE and Nissan LEAF.

While it has some interesting implications for mass production of the platform and lowering the price, you shouldn’t hold your breath since Arnaud Deboeuf, the executive in charge of the Renault-Nissan alliance, warned of a long product cycle and media reports suggest that the next generation – not to be confused with a design refresh – shouldn’t come to market until 2020.

Deboeuf talked briefly about the new platform to reporters at a media event in Paris this week (via Auto News):

“The cars will have different exterior styling but will share underpinnings and electric motors, said Arnaud Deboeuf, senior vice president of Renault-Nissan BV, the alliance’s strategic management unit.”

It will be interesting to see how the two automakers will pull this off considering that the ZOE is significantly smaller than the LEAF.

During the first week of January, Nissan CEO Carlos Ghosn is set to deliver a keynote speech at CES 2017. It is rumored that he will unveil an electric vehicle with a 60 kWh battery pack for over 200 miles of range. It still remains to be known whether it will be the refresh version of LEAF, which is expected to come with the 2018 model, or a brand new electric model from the Japanese automaker.
